Deactivate a model's filterable conditions using Javascript

In the same function, before I set the model's condition, I want to deactivate all other filterable conditions so that I can be sure that the user is seeing the right set of data. I know how to deactivate conditions by name (as described here: http://community.skuidify.com/skuid/t...). But we can't know for sure at runtime how many filters there are, so this is too hard-codey. And I don't want to deactivate all conditions for the model, just filterable ones. Is there a simple property to check perhaps?
